Figure 10 is a view of one of the coil forms .per se, as shown 1n Fig. 1.

Referring to the drawings, the numeral 10 designates the tubular member which is adapted to be fastened upon a rotary device, such as the shaft of an electric motor or the like, and which carries the substantially cruciform member 11 having the respective terminals 12, 13, 14 and 15. The front face of each of these terminals, as clearly illustrated in Figure 4, is provided with two parallel groove-forming edges 16 and which, as illustrated in Figure 1, embodies four of such groove-forming members incruciform shape and for the reception, respectively, and for sliding movement, of the various adjustable elements of the present construction. The

.members or terminals 14 and 15 have blocks 17 and 17 mountedin this groove-forming portion so as to be laterally adjustablepr slidable, there being` provided the radial slots 18 and 18 for reception of the respective pins 19 and 19', said pins being connected to and bodily movable with the slides or blocks 17 and 17 and being extended through the'arcuate slots 20 and 21 of the operating disk 21. By this means, as the disk 21 is oscillate'd through the medium of its operating handle 22, the slides 17 and 17 are moved radially to or from the center of the present device.

Each of the respective blocks 17 and 17 are provided with the dove-tailed portions 23 to receive the male member 24 of the adjustable reel section carrying member 25, the screw 26 engaging the same and being mounted in the clamping -terminal 27 so that said screw can be rotated to adjust the position of the mem! lber 25 relatively to the slide and then be locked, due to the clamping nut or bolt 28. Each one of these reel-carrying members 28 is provided'with an apertured offset' 29, the

.purpose of which will presently appear..

The slides 30 are mounted in the dove-tailed grooves 30 of the terminals 12 and 13, and each of these slides is provided with an olfset 33' in which is mountedfor v rotation the adjusting screw 32, and this screw, in turn, is connected to operate its respective T-shaped member 31a and 31b to regulate the adjustment thereof with regard to the slide, whereas the slide itself has movement imparted thereto through the mediumgof the pin 35 which is mounted for radial movement within the slot 34 of the support 10 and for actuating movement in the arcuate slot 36 of the oscillatory plate.

Mounted upon and within the respective T-shaped members, thatis,'in the lateral terminals thereof for adjustment and to be bodily carried thereby are the reel section carrying blocks 37 and 37, 37'HL and 37b, andy these blocks are mounted in pairs, so as to be controlled for adjustment by means of the respective rightand left-hand screws 38 and 38', which, when operated, tend to move the blocks, as, for instance, 37 and 37 to or from the verticalcenter line, as viewed in Figure 1. By this means, these blocks may be adjusted relatively to the center line, as viewed in Figure 1, whereas the 'iT-shaped members are adjusted relative to the horizontal line, and then after being adjusted, by means of the operating plate 21, they are moved with the respective section-carrying slides 17 and 17 to or from the center of 'the present structure, as and for the purpose hereinafter set forth.

Each one of the respective blocks 37, 37',

37a and 37b are provided with the respective reel section receiving projections 39, 39', 39L and 39", and each one of which carries its respective reel section of a type to be laterl described. y

As the construction of these various type reel-carrying members are identical, the description of one will suiiice for all. I

As viewed in Figs. 1 and 10, a support55 is detachably connected to four of the projections 29 and each carries the pair of segmental coil formers or plates 56 and 57 a countersunk set screw 58 being employed to attach the outer plate 57 at its desired adjustment upon the rod.

As'lviewed in Figure 8, each member consists of the supporting shank 42 which is adapted to be secured to its respective supporting member 29 through the instrumentality ofthe set-screw 40. The o-set portion 43 carries the cylindrical portion 44 provided with the spaced teeth 45 which form wireand coil-receiving receptacles throughout the full length' of the membertorsection of the reel, so that the wires W may be positioned therein and securely clamped at the initial winding of the' reel' through the eccentric roller 46 carried upon the rod 47, and journaled in the apertured lugs 48, a manipulating handle 48 being provided to release the wires, whereas the insertion of the wires between the eccentric roller 46 and the portion the wire lwill tend to lock the clamp and hold the wire firmly in position.

By this construction, it will be noted that a plurality of coils, one to each space between the teeth 45, may be formed, but in the form shown in Figure 8, the width of the respective coils will be according to the space, whereas in the structure shown in Figure 7, the adjustable space-forming members 55 are attached by'means of set-screws 54 to the shank 44', the portions of this construction that are identical with that shown in Figure 8 employing similar numbers with the prime indication.

In this construction, the wires, instead of being clamped by a single eccentric clamping device, as in Figure 8, are clamped by individual clamping devices consisting of the pin 56 and pivoted locking eccentric 57.

lt is desirable, when a plural number of coils are being formed, that the outer ends of the respective reel section forming members be stabilized or held in their fixed adjusted relation and with as little vibration as possible, as the winding of the coils therearound has a tendency to draw Jthe free ends inwardly, and in order to preventthis and thus insure the proper shape to the coils, there are provided a plurality of plates 49, as particularli,7 viewed in Figure 6, the terminals of` which will movably the members 41, while the slotted portions 51 meet or cross at the center and are secured together by the winged bolt 52.' By this means, the device may be readily placed in position and removed, and, as' before stated, the stability of the reel insured.

As shown in Fig. 11, each rod 55 is provided with a pair'of adjustable disks 62 and 63, whereby coils of loop form or irregular shapes may be constructed, the space between the disks regulating the thickness of the coil or loop to be constructed.

fit upon the outer ends of As it is desirable to lock the reel in extended 'y position, the lock, as shown in Figure 9, is employed, wherein the headed locking pin 59 is controlled by the lever 61, carried by the handle 22, the spring 62 normally holding the pin seated in the recess 60 of the base 1-1.

Graduations G are formed on various faces of the devices so'that exact adjustments for varying sized coils may be quickly set.

From the foregoing description, taken in connection withthe drawings, the operation of the presentdevice'is readily understood, land the advantages fully appreciated, but, briefly stated, it is as follows The respective reel section forming members 41 are positioned in'place and the respective slides are adjusted in the cruciform carrying member, so that these membersassume, `when fully extended, the size .of the coils to be formed. The terminals of the wires are then positioned through the medium of the clamps shown in the respeiftive views,

ico

Figures 7 andv 8, and the device rotated through any means, such as an electric motor,

as the spindle 10 of the support is adapted to winding machine has made and tostop the same when a sufficient number of coils have been wound between the respective receptacleforming members of the reel sections. When this is completed, the handle 61 is depressed and the handle 22 is oscillated so as to retract the slides, and, in turn, the reelsections or reel-forming members 41, and by such cpntraction permitting the easy removal of the respective coils from the reel. Where the device as shown in Figure 6 is employed, the same is inserted in place before the initial Winding operation. By loosening thumb screw 52, this device will collapse. to permit of the removal ofthe coils from the reel.

It is evident that with a device of this character provided with so many adjustments that various shapes and sizes of coils, as regards circumference, may be produced simultaneously, and also, where desired, coils of considerablev bulk, that is, with greater turns, can also be formed, thus providing in this one winding machine a universal device for use in constructing many sized coils, and also a plural number of coils at the same time.

It will be seen that this device is so constructed as to expedite the quick setting up lfor various sizes and shapes of coils, and for the` receiving of various attachments or devices for forming the coils. l 'I claim 1.
